Workflow
- Attribute spend to pipelines and tables.
- Rank by cost and by wasteful ratio (scan vs needed).
- Propose changes ordered by savings / risk.
- Define the unit metric to watch afterwards.
Inputs
- Billing/usage export
- Pipeline and query logs
Outputs
- Cost attribution
- Ranked opportunities
- Per-change expected saving
- Guard metric
Guardrails
- Never applies a change
- Flags any recommendation that could change results
Example
